Grasses allow us to read the landscape: from soils, habitat, disturbance and past land uses. They form a critical component of the biodiversity and with nearly 11,000 species, this is the fourth largest plant family. This workshop consists of an intensive, hands-on approach incorporating both classroom work and field study.&nbsp; Identify warm season grasses in the field and lab, learn the specialized terminology and distinguishing features, discuss their ecology, and practice identifying species from keys.</span><br /><div class="field field-name-body field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even" property="content:encoded"><span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px; line-height: 18.2px;"><strong>Instructor:</strong> Scott Namestnik, senior botanist, Orbis Environmental Consulting</span><br /><span style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 13px; line-height: 18.2px;"><strong>Notes:</strong> Held both indoors and outdoors.

To see this, pull on the end of the spikelet and see if it breaks off somewhere along the spikelet (<em>C. odoratus</em>) or&nbsp;if the entire spikelet breaks off as a unit (<em>C. esculentus</em>).&nbsp;

The families should be easy to distinguish.&nbsp; Rushes (Juncaceae) have sepals and petals (or collectively tepals) surrounding the pistil and stamens, giving them, on a minute scale, the look of a "typical" regular flower such as a lily.&nbsp; Grasses (Poaceae) and sedges (Cyperaceae) have flowers that&nbsp;are evolutionarily advanced&nbsp;and consist of just the most important parts for reproduction, the pistil and the stamens; the perianth is highly modified in these families and doesn't look like what you would think of as petals and sepals.&nbsp; In the grasses, the flower is usually subtended by two bracts, known as the lemma and palea, and each floret (as these structures are known collectively) or group of florets is subtended by additional bracts known as glumes (usually two, sometimes one or absent).&nbsp; In the sedges, the flower is subtended by a single bract, called a scale.&nbsp; Grasses (nearly all of them, at least) have hollow stems with solid nodes.&nbsp; Most sedges have solid or pith-filled stems without swollen nodes.&nbsp; Most grasses have overlapping sheaths; sedges have fused sheaths.&nbsp; Grass leaves are typically flat or rolled; sedge leaves are usually V- or W-shaped in cross-section.&nbsp; There are other differences, but understanding these basic differences should at least get you in the right family.<br /><br />As far as sedges go, <em>Carex</em> is the most diverse genus.&nbsp; Being able to recognize groups or sections of the genus that have similar characteristics is often a very helpful tool because it allows you to narrow down your species options substantially.&nbsp; Some of the other more species rich genera in the family Cyperaceae include <em>Scirpus</em>, <em>Eleocharis</em>, and <em>Cyperus</em>.&nbsp; In the genus <em>Cyperus</em>, the flowers are perfect and there are no perigynia (paper-like sacs surrounding the female flowers) as there are in the genus <em>Carex</em>.&nbsp; The scales subtending the flowers in <em>Cyperus</em> are folded in half, not flat or rounded as they are in many other genera.&nbsp; Morphologically, the genus that looks most similar to <em>Cyperus</em> in the United States is <em>Dulichium</em>.&nbsp; The flowers on plants in the genus <em>Cyperus</em> lack the long persistent styles (the tubercles) that&nbsp;are present in flowers on plants in the genus&nbsp;<em>Dulichium</em>, and <em>Dulichium</em> has axillary inflorescences whereas <em>Cyperus</em> has terminal inflorescences.<br /><br />Within the genus <em>Cyperus</em>, as within the genus <em>Carex</em>, the species can be organized into several natural groups (subgenera) that share morphological characteristics.&nbsp; Within subgenus <em>Cyperus</em>, which has flowers with three stigmas (as opposed to two), spikelets along a conspicuous rachis (as opposed to being in digitate or glomerulate heads), and rachilla (the axis to which the flowers are attached) that disconnect from the rachis (the axis to which the spikelets attach) only at the base (as opposed to having rachilla that disconnect beneath each scale), two of the most commonly confused species in the Great Lakes region are <em>Cyperus esculentus</em> and <em>Cyperus strigosus</em>.&nbsp; <em>Cyperus odoratus</em> is also often confused with these two species, but it is taxonomically placed into subgenus <em>Diclidium</em> because the rachilla disconnect beneath each scale, not at the base of the spikelet.&nbsp; If you pull on a spikelet of a species in subgenus <em>Diclidium</em> from the end of the spikelet, the spikelet will break somewhere in the middle; pulling on a spikelet of a species in subgenus <em>Cyperus</em> from the end of the spikelet will result in the entire spikelet being removed from the rachis in an intact unit.<br />﻿<br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto;

First take a look at the inflorescences.&nbsp; Usually, <em>Cyperus esculentus</em> has spikelets that are orangish in color (see photo above), as compared to the yellowish or straw-colored spikelets of <em>Cyperus strigosus</em> (see photo below).&nbsp; In addition, the spikelets of <em>Cyperus esculentus</em> aren't usually packed into the inflorescence as tightly as those of <em>Cyperus strigosus</em>.<br /><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto;

In the two photographs below, the structure in my hand is a&nbsp; single spikelet, made up of several flowers, each subtended by a scale.<br /><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto;

However, you should be able to tell that in the <em>Cyperus esculentus</em> spikelet photo (above), the scales are shorter (approximately 2-3 mm long) than those in <em>Cyperus strigosus</em> (3-4 mm long).&nbsp; Although this difference isn't much, with some experience, you can begin to notice the short scales of <em>Cyperus esculentus</em> and the "long" scales of <em>Cyperus strigosus</em> on a quick inspection with a hand lens.<br /><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto;

Grasses allow us to read the landscape: from soils, habitat, disturbance and past land uses. They form a critical component of the biodiversity and with nearly 11,000 species, this is the fourth largest plant family. This workshop consists of an intensive, hands-on approach incorporating both classroom work and field study. &nbsp;Identify warm season grasses in the field and lab, learn the specialized terminology and distinguishing features, discuss their ecology, and practice identifying species from keys. <br /><br />Instructor: Scott Namestnik, senior botanist, Orbis Environmental Consulting<br />Notes: Held both indoors and outdoors. Please dress for the weather each day. Limit 20<br />Supplies: Please bring a water bottle, a hand lens, and wear sturdy, closed-toed shoes for walking over uneven terrain.

Because of this geographical distribution, it is a species of conservation concern in several states.&nbsp; It grows in wet to moist conditions, such as in bogs, fens,&nbsp;and coniferous or deciduous forests, but also on sandy or rocky ridges or dunes near the Great Lakes.&nbsp; The genus name <em>Geocaulon</em> means "earth" (Geo-) and "stem of the plant" (-caulon),&nbsp;which is a reference to the long slightly subterranean stems (rhizomes).&nbsp; The specific epithet <em>lividum</em> means "lead-colored," which could be a reference to the flowers, which range from green to purple in color.<br /><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto;

It differs from <em>Comandra</em> in having green to purple flowers (versus white in <em>Comandra</em>), axillary inflorescences (versus terminal in <em>Comandra</em>), and orange-red fruit more than 7 mm in diameter (versus green to yellowish fruit up to 6 mm in diameter in <em>Comandra</em>).&nbsp; In each cymule on a <em>Geocaulon lividum</em> plant, the central flower is perfect, whereas the other one to two flowers are staminate; <em>Comandra</em> has all flowers perfect in each cymule.&nbsp; For comparison, <em>Comandra umbellata</em> is pictured below.&nbsp; Vegetatively, <em>Geocaulon lividum</em> may be confused with a member of the genus <em>Vaccinium</em>, which would have woody stems and leaves with different venation and texture.<br /><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto;

The range of the species&nbsp;follows the Atlantic Coast south, around Florida, and along the coast of the Gulf of Mexico to Texas.&nbsp; Like several other species with which it often grows, this modest pink-flowered plant is also disjunct in the Great Lakes region, making it a unique part of the flora in this part of the country.&nbsp; <em>Triadenum virginicum</em> grows in bogs, interdunal swales, and wet meadows.<br /><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto;

It&nbsp;has been treated as a variety of <em>T. virginicum</em> in the past, but most botanists now consider the two to be distinct species.&nbsp; The sepals of <em>T. virginicum</em> are longer (greater than or equal to 5 mm long versus up to 5 mm long in <em>T. fraseri</em>) and&nbsp;sharper pointed (acute to acuminate versus obtuse in <em>T. fraseri</em>), and the styles are longer in <em>T. virginicum</em> (more than 1.5 mm long versus less than 1.5 mm long in <em>T. fraseri</em>).&nbsp; In addition, <em>T. fraseri</em> is rarely found with open flowers in the field (but they are said to open after spending an afternoon in a vasculum!), whereas it is not uncommon to see <em>T. virginicum</em> with open flowers.<br /><br />Plants in the genus <em>Triadenum</em> were formerly treated as part of the genus <em>Hypericum</em>, but they are now distinguished from <em>Hypericum</em> due to petal and stamen characteristics.&nbsp; The petals of <em>Triadenum</em> are&nbsp;pink or flesh-colored (versus yellow in <em>Hypericum</em>).&nbsp; The stamens of <em>Triadenum</em> are in three groups of three and alternate with three large orange&nbsp;glands (versus being of various number and lacking glands&nbsp;in the flowers of&nbsp;<em>Hypericum</em>).&nbsp;&nbsp;This unique characteristic of the flowers of plants in the genus <em>Triadenum</em> is the origin of their Latin name, as <em>Triadenum</em> means "three glands."http://getyourbotanyon.blogspot.com/2013/11/triadenum-virginicum.htmlnoreply@blogger.com (Scott Namestnik)4tag:blogger.com,1999:blog-675935764461060188.post-8260133702538265295Tue, 29 Oct 2013 06:21:00 +00002013-10-28T20:22:09.456-07:00ClematisPlant QuizPlant Quiz - Answered<div class="separator" style="clear: both;

It’s a native of dry sand country and adds a lot of color and character to black oak savannas. &nbsp;The leaves occur in three different types: one lobe, two lobes, and three lobes. The crushed leaves and twigs have an unusual but pleasant smell. The cut wood is beautiful and has a pungent chemical smell that is also very good. And of course, the roots have that wonderful root beer smell and flavor, long cherished for sassafras tea. Experts now say the tea can cause stomach cancer, but I’m starting to think so does breathing the air and drinking the water.<o:p></o:p></span></div><br /><div class="separator" style="clear: both; margin: 0px; text-align: left;"><span style="font-family: 'Times New Roman', serif; font-size: 12pt;">Of this remarkable and very attractive tree, Thoreau wrote the following: "The odoriferous sassafras, with its delicate green stem, its three-lobed leaf, tempting the travelers to bruise it, it sheds so rare a perfume on him, equal to all the spices of the East.

This mint is found at various locations in states along the east coast of the United States, but it is also disjunct in the Midwest/Great Lakes region, specifically in Michigan, Indiana, Illinois, and to a lesser extent in Missouri.&nbsp;

Those who have compiled the National Wetland Plant List seem to think of this species as a pure wetland plant, as it is ranked as OBL or FACW in all regions in which it occurs.&nbsp; That would mean that it is almost always found under wetland conditions but that it is occasionally found in uplands.&nbsp; Many of the references I checked state that this species is found in moist soils, often near lake margins, and also in bogs.&nbsp; This is of course true, but it is also found in dry acid soils of prairies and savannas.&nbsp;
